What does omsois and diffusion have in common

Diffusion and osmosis are passive processes, meaning they don't need energy to occur. Both are spontaneous processes ... In osmosis, water freely moves across a membrane from an area of low solute concentration, or hypotonic solution, to one of high solute concentration, or hypertonic solution.

osmosis is the movement of water molecules. similarities: the similarities in osmosis and diffusion is that they both equalize the concentration of two solutions into a membrane. they both work together to move water molecules from a area of high concentration to a area of low concentration.
